Shedding Light On DNA Replication

Undergraduate biology students could be forgiven for thinking that scientists have DNA replication all figured out. After all, textbooks present the models of replication so matter-of-factly that it's easy to forget that many details are understood poorly, if at all. Recently published research sheds light on some of the gaps in our understanding of this key cellular process.

During replication, the DNA must be unwound and separated into its two strands by an enzyme known . . .
